Notes on Electrical Characteristics:
1Guaranteed by design and characterization, not 100% tested in production.
2 Slew rate measured through Vswing centered around differential zero
3 Vxabs is defined as the voltage where CLK = CLK#
4 Only applies to the differential rising edge (CLK rising and CLK# falling)
6 All Long Term Accuracy and Clock Period specifications are guaranteed assuming that REFOUT is at 14.31818MHz
5 Defined as the total variation of all crossing voltages of CLK rising and CLK# falling. Matching applies to rising edge rate of
CLK and falling edge of CLK#. It is measured using a +/-75mV window centered on the average cross point where CLK meets
CLK#. The average cross point is used to calculate the voltage thresholds the oscilloscope is to use for the edge rate
calculations
7 Operation under these conditions is neither implied, nor guaranteed.
9 See PCI Clock-to-Clock Delay Figure
8 Maximum input voltage is not to exceed maximum VDD
